Is The Front Panel Worki

I haven't installed the new driver yet for my SB X-Fi Platinum. I need the Aux inputs on the front panel for my WX5 Wind Controller. Are they acti've with the new driver or do I need to wait for some other software?

the main reason i bought my Audigy2 Platinum was so i could plug my shure sm57 into the /4inch mic jack for recording guitar i even use it for voice chat, sure beats a cheap 0 dollar mic, and i use the rca jacks for recording from tapes, records or plugging a keyboard in, if i cant do that it doesnt matter what sound card i have. From what i've read and heard about the X-Fi, it works for some and not for others. the front panel connectors i use on a daily basis. hopefully by tomorrow ill have the audigy drivers to test out.

Audigy 2 ZS Newbie Question? Is my front panel working rig

WHOA! I'm new with this card but not posting..don't know what happened with that blank post..(The cat stepped on the "Enter" key...Yea..thats it..thats the ticket)
Anyway, I just hooked up my card and installed my front panel and I have a couple of dumb questions:
. Should the front panel be lit's What is the led abouve the MIDI for? Does it just light when MIDI is pluged in?
2. I have almost no volume at the headphone jack. I have heard others say that it mutes their speakers when they plug into the HP jack, Mine does not.
3. Wait, is that an LED or the pick up for the remote? Hmmm..just thought of that?
The remote does work, albeit poorly. The firewire on the front panel works, I can't test much else. I guess my main question is: Does the front panel light up? It just looks like that there is no power getting to it..
I want pretty lights!! :-)
Thanks for help
Phil

oh man thanks a lot! i knew about that option too, but i completely forgot about it!! lol
and let this be a reminder to anyone else dumb enough to forget about that little option!
thanks again

Mic socket wont work on the front panel of fatal

When i connect my headset & mic to the headphone & mic socket on the front panel, the mic dosent seem to work even though if i blow in it i can hear myself thru the headphones a little but if i turn up the mic volume on the front panel it makes a weird loud noise, the sound comes through the headphones ok. Many thanks for any help given.

Have you tried turning on the microphone +20 dB boost?
It's on the plus sign of the recording source ( when set to microphone in the mixer ) in the X-Fi mixer.

Is there a way to use the built-in Datalogging and programmatically log the front panel while the vi is running?

I would like to use the built-in Data Logging feature. There is the "Log at Completion" option, but is there a way to programmatically make a new log record while running? I looked around in VI server and couldn't find any methods that would do that. Currently, I am grabbing all of the front panel control references using VI Server and if there are any changes, the changed values are written to a log file along with a date/time stamp. I'm mostly dealing with buttons, which simply change from 0 to 1 or 1 to 0, so it's not too hard to visualize what was pressed. It works okay for reconstructing what happened, but it would be much nicer to use the built-in fe
ature because you can "replay" directly onto the front panel and actually see what the changes were. However, without being able to programmatically make a new log, it won't work for me.

Jake,
There are several options here.
I would suggest using your own code for datalogging. The datalogging you are referring to is primarily for debug, and one shot datalogs of front panel indicators (and controls?), not including graphs, etc.
If you go to the file functions, you will see a menu for datalogging. These functions will allow you to save your data, as you need it, simply, and in a compact format.
I recommend opening the datalog file, doing all your file operations, and closing the file before the program is complete. There are several examples of this in the examples database.
Good luck

How can I display a changing variable in a subvi on the front panel of the main vi as the subvi is excuting

In the document attached the vi on the right is sub to the vi on the left. On the subvi on the right the variable "Field Reading" is continuously updated on the front panel of the subvi as the "for" loop is executed, but only the last value of the variable is updated on the main vi front panel which is what is expected. My question is how can I display the changing value of "Field Reading" on the main vi front panel as the "for" loop in the subvi is running?
Thank you.

Hopefully I can explain it well enough. It really is simple.
1) Create an empty global variable and call it something like User Interface References.vi
2) For each and every control and indicator on your front panel, right-click and select Create/Reference
3) Place these references wherever you like (I use a series of Event cases to perform my initialisation and these all live in one of these event cases). They can be placed anywhere in the main vi.
4) For each of the references, right-click and select Create/Indicator
5) Moving to the front panel, Cut all the indicators and Paste them in the global variable (eg. User Interface References.vi)
6) Moving back to the block diagram, wire the global variable to each of the references and select the same named global variable.
All the hard work is now done (until you add another user interface terminal). You should now have something that look as shown below, [except the reference labels would be to the left (not sure why the snippet put them above)]. In my latest program I have 82 references!
Done. You can now access all your front panel controls and indicators anywhere in your program as shown below.
You can just select Value in most cases, but in this particular case I wanted to fire off an Event to do some things (log the alarm) as well as just update the value. So, this is another bonus with the method.
Hopefully this all makes sense. If not, let me know.

How do I input data to a table on the front panel and stop the program immediately as button is pressed?

What should I do if I want to display on the front panel in real time the values from Polarizer #, P1, P2 and the last calculated value (P2/P1 * 100) called T% in a table or some graphical representation like that? What would I have to do? It could just be Polarizer # and T% if that would be simpler. I just want to let the user know the values in a list, spreadsheet or table as they go. One last thing is that I would like to be able to stop the program at any point in time as soon as the stop button is pressed. As of now, when the button is pressed it goes through the iteration currently in progress and then one afterwards. I want the program to end as soon as the stop button is pressed no matter what sequence it is. What can I do to achieve this? Could you give me an example or modify my program to show me this.
Thanks,
Steve

Put a single frame sequence structure around your stop button and then wire from the error cluster going into the error handler to the edge of the sequence structure. Now your code will stop at the end of the current iteration. To see why this works, watch you code execute with execution highlighting turned on and review the section of the manual talking about "Dataflow".

How to display the status of a SubVI on the front panel?

Hi,
I am writing a program to control an instrument through a serial communication port. The control and communication functions are integrated in a SubVI and they work fine.
In the front panel of the main VI, I want to add some indicators to display the status of those controls in real time, such as using some LEDs to show whether the program is running in some loops of the SubVI, or use some indicators to show some variables in the SubVI.
I tried using global variables, but I can't make them work in real time (or maybe I didn't do it right). The values of the global variables are actually changing on the fly, but the indicators on the front panel wouldn't reflect those changes until the program return
ed from the SubVI.
Is there a way to do this in Labview 6.0.2?
Your earlist help is very much appreciated.
Best regards,
Hua

Hua,
I have attached an example in which a front panel boolean indicator is toggled in the subvi. Also, a front panel stop button is used to stop the loop execution in the subvi. References are passed to the subvi instead of the actual control values.
Without seeing your code I'm not sure what was going on with the globals, but you had to have a data dependency somewhere which was keeping the code from running until after the execution of the subvi. The code must be totally independent of the subvi in order to run. Also, in order for the update to work it would have to be operating in a loop.

Is it possible to use a Case Structure to hide numeric indicators on the Front panel when they are not in use?

I am rather new to LabVIEW, have only been using it for about 1.5 weeks as of this post, which means I may be missing something rather obvious due to ignorance, but is there any way to have my front panel change as my case changes due to user selection of a certain case via the front panel?
The goal of the program is to make a simple layout for a user that is using the digital multimeter that the proposed code is designed for and I don't want tons of numeric controllers and such clogging up the screen space that don't work with the function the user is using to measure with.
Thanks in advanced.

Check out the property node for the controls
Visible Property
Short Name: Visible
Requires: Base Package
Class: Control Properties
Displays the front panel control.
This property is similar to the Show Control and Hide Control options on the shortcut menu of a control.
Also look at the TAB control to control which controls are available to your user.

I want to save an image of the front panel, (with data), after every VI run

When I try to copy the front panel (using a select all), and paist to paint, all the data in the graphs show up as they did after the last run, but the data in the charts dissapear. The chart itself is copied but the data is not. Any ideas on how to solve this?
Thanks,

This Knowledgebase also has some information on programatically saving VI images
http://digital.ni.com/public.nsf/websearch/942DAA35C7B35616862565FE005F713F?OpenDocument
(KB 197BB7VJ if the link doesn't work).
Note that you don't have to put the code in the VI you are running in order to save it to a file, so you don't actually have to modify your VI. You can just run a seperate VI that uses the VI name from the first one (I've attached a VI which could either be run standalone or used as a SubVI, as well as an example of using it as a SubVI).
If you don't want to do it programatically you could just hit the print screen button on your keyboard and then paste it into paint and crop off the extra windows stuff.

Dataflow Conflict appearing on the front panel

Hello,
my vi is almost done but I still have a problem with the front panel. I think it's about data flow conflicts in my vi.
When you run my vi, you will see the pop-up window to ask you about putting a file path, adjusting the units, selecting data to save and plot. Then you might want to change the units, turn on-off all light and ok buttons to choose which data you want to save. Then click RUN.
The problem is; supposedly all buttons are on as default, if you turn off some saving or plotting buttons for not choosing to save, then click RUN, after that all buttons are on again even though you turned them off before running. They should stay off if you didn't select to save them. The condition of the main data stream always goes back to be the same before running (only light and ok buttons).
Do you have any ideas how to solve this problem?
Thank you in advance

Value Measurement Project.lvproj ‏2 KB

You have what's called a race condition which commonly creeps into programs that use local variables. If you look at your first while loop you read in the current "Main Data Steam" value from the control and store it in a shift register. After the event structure exits you write the value from this shift register back into the control and in the process overwrite any changes the user may have made.
One quick and dirty solution would be to handle the Value Changed event for "Main Data Stream" in your event structure to update the shift register whenever the user changes values in the control.
A better solution would be to get rid of the shift registers and move the local variables into the event structure. As long as the "lock front panel until event completes" option (I'm not sure of the exact wording and I'm working in LabVIEW Base at the moment so I can't check it) is selected it will ensure that you don't run into a race condition (you know the value can't change inbetween you reading in the value and you updating the control).
Better yet would be to avoid local variables wherever possible. This is just general advice and not something I can make much more tangible without knowing the details of how you want your application to behave.
Hope this helps,
Simon

Screen capture of the front panel automatically

I've got a VI that analyzes a data file and outputs a graph, some numbers/notes, and a pass/fail message to the front panel each time we run it. I want to be able to automatically save all that data into one easy-to-access file (no html) after running it, and ideally this would be accomplished by just capturing the screen of the front panel and saving it as a .jpg.
I've looked up how to do this on the forums and searching the web, but no solutions have come up. I've looked at the "Get Image" method, but that only lets me get the image of one object in the front panel, and not the entire front panel screen. I read something about referencing the front panel as an global, and inputting that into the "Get Image" method, but I can't get that to work and don't know if that's possible.
Is there a way to make a straightforward automatic screen capture of the VI front panel? How can I program that? (Manually using the "pinrt screen" function off the keyboard and copying and pasting it won't be feasible for this application).
-- Thanks for the guidance

No sure why you couldn't find a reference to it but there is the VI method Get Panel Image.

How can I make an area of the front-panel have scroll bars?

I'm writing a VI that provides many options to the user. The front-panel is large and contains many controls ~130 of them, it's divided up visually to match the workings of the system the VI controls. One particular functional block has very many control options though these are rarely used. I can't fit all of the controls I need onto the screen area I have available.
What I would like is a way of making an area of the screen with scroll bars on it. I don't need any more than that, just an expansion of the front-panel area I have available. The "Sub-Panel" feature provides the scroll bars. But, a Sub-Panel is a way of accessing another VI, I don't want to do that. I could put the extra controls on the far-left or far-right of everything else and get the user to scroll the main scroll bars at the edges of the screen. The problem with that is that I it would mean couldn't lay out my front panel to match the system block-diagram as I have so far.
Does anyone know how to do this?
Solved!
Go to Solution.

I know I can show the scroll bars at the edge of the VI. In my case that's not very useful. The front panel shows a block diagram of a system. It's made up of a set of clusters which control various parts of the system. I want to keep this layout because it's very useful in explaining to people new to the system how it works. I inherited that approach from a previous iteration of the program for an older system. The problem I have is that the new system has far more control parameters for one of the blocks. Unfortunately it's one of the blocks in the middle of the block diagram. If it were one at the left, right, top or bottom it would be no problem because the main scrollbars could be used.
I can use a tab-control, that's my fall-back plan. The problem is that would be abusing the purpose of the tab control. In a tab control each tab is supposed to deal with a group of controls that have a common connection. So, all the things in tab #1 are supposed to be connected in some way and all the things in tab #2 are supposed to be connected in some way. There not supposed to be a way of gaining more screen space.
The controls I'm dealing with are numeric controls, switches and rings.

Using a "menu ring" feature on the front panel with event structures

hello - right now i have many event cases controlled by many "ok buttons". i would like to use a menu ring on the front panel to save space from all those buttons, but i don't see how it will work with all the individual event cases. currently each event is tied to a single button, and the menu ring acts as one thing on the block diagram so i can't tie an event to a choice in the menu. any suggestions? thanks....

Alternativley, you could use an enum control instead of a menu ring. It will name the cases according to the selection automatically.
If you want to use a menu ring and strings, you could do something like in this image.

Trouble getting a subvi to update a graph in real-time on the front panel

Hi All,
First post here, so play nice =). I am trying to update a graph on the front panel from within one of my subvis, however it does not update it in real-time. It will only show the completed graph after the subvi finishes running. I have tried to use references/property nodes and I have also tried using my chart as a global variable, but neither of those methods have worked (I am probably doing it wrong). Can anyone provide a detailed walk-through of how to do this using either one of those methods? Or perhaps even a different method?

ModusPwnens wrote:
This is how you do it, right?:
Try this for a quick demo of the reference method:
Create a VI as shown in the image.
Select only the while loop and do "edit...create subVI" (as shown). (you will get a subVI that contains the needed connectors and is alread wired to the reference)
Run the main VI, and the chart will update every 200ms.
Note that this is only a draft and many things are missing. (For example, the subVI cannot be stopped at the moment. Also, you want a graph, and not a chart.)

How to run a subVI without poping up normally, but when clicking a button, popup the front panel?

I know pop-up the front panel of a subVi when called by selecting VI Properties>>Windows apperence.
But what I need to do is: always run the SubVI inside the parent VI as the nornal subVI do without poping up. But when I click a button"show front panel", the SubVI popup the front panel.
Is there anyway to do this?
Thanks,

ossoo,
You can use a static VI reference to the subVI and then use the Front Panel Open invoke method to show the front panel when you want. I have attached two VIs that show this. I saved these VIs for LabVIEW 2009 so you should be able to open them up and run them in 2009 or later. Add.VI is the subVI that you are calling. The Caller.VI is just a While Loop that contiually calls the Add subVI. Inside of the While Loop is also a Case Structure with a Static VI Reference (you might need to change the path this is pointing to after downloading the VIs to your computer for this to work) and the Front Panel Open invoke method. You can run the Caller.VI and interact with the main Front Panel as normal and see the subVI but then you can click the Open subVI? boolean button and it will open the subVI's front panel. You can continue to interact with the main front panel and see the values update on the subVI's front panel as well. You can just close the subVI's front panel when you are done viewing it. Does this help?
